The Matthew effects suggest that children who struggle when learning to read are less likely to read for pleasure later in life compared to children who ease into reading quickly. One aspect of early literacy instruction that might hamper reading progress is learning to read simultaneously in two languages. Despite the long-lasting and widespread…

Two experiments investigated whether exposure to Chinese characters and pinyin would facilitate oral vocabulary learning for Chinese as a first (L1) and second (L2) language learners. In Experiment 1, 48 second Chinese graders studied 15 made-up associations between spoken labels and pictures accompanied either by no orthography, by pinyin, or…

The rapid growth of Mandarin Chinese and English dual-language (DL) programs and the differences between these two languages have fostered the need to investigate the early literacy performance of young students in a Mandarin/English DL program. This study used the interactive transfer framework (Chung et al., 2019) to understand the Mandarin and…

The present study examined oral language growth differences in a sample of 256 Greek-speaking children with and without literacy difficulties (LD), during the first two elementary grades. Measures of vocabulary, phonological awareness (PA), morphological awareness (MA), and rapid automatized naming (RAN) were administered in both grades for the…

This study examined the oral language skills of grade-two anglophone children enrolled in French Immersion and English-stream programs. The study had two objectives: (1) to compare performance between the groups on measures of receptive vocabulary, narrative comprehension, and narrative production (i.e., structure and language) in English; and (2)…

This study reports on a small-scale, longitudinal investigation on L2 Spanish oral development by English-home language (EHL) learners in an English/Spanish Two-Way Immersion (TWI) program in rural, eastern United States. It examined EHL learners' oral ability in L2 Spanish based on longitudinal assessment data from Kindergarten, Grade 2, and…

Academic language has been shown to significantly contribute to success across school subjects. However, to date, there are no empirical studies addressing its development across primary school age. The present study investigated the growth of academic vocabulary and influential conditions from Grades 2 to 4 based on a newly developed and…

The simple view of reading (SVR) model proposes that reading comprehension is the product of word decoding and language comprehension, and that both components make independent contributions to reading skill (Gough & Tunmer, 1986). The model posits that there are good readers and three types of poor readers--dyslexic, hyperlexic, and garden…

This study examines vocabulary growth rates in first and second languages for Spanish-speaking and Cantonese-speaking English language learners from kindergarten through second grade. Growth-modeling results show a within-language effect of concepts about print on vocabulary. Language exposure also had an effect on English vocabulary: earlier…

Is it best to learn reading in two languages simultaneously or sequentially? We observed second- and third-grade children in two-way "dual-language learning contexts": (a) 50:50 or Simultaneous dual-language (two languages within same developmental period) and (b) 90:10 or Sequential dual-language (one language, followed gradually by the other).…

A Mandarin/English two-way immersion elementary program is described from its inception and implementation through the fifth grade, the culminating year of the program. All students in all grades were assessed on their oral/listening, reading, and writing performance in Mandarin using program-created assessment measures. Fifth-grade students also…
